Study Objectives“Where is it coming from?”

Identify and rank sources, including transportation sources, of NOx, SO2, Airborne Particles and CO, using mobile monitoring techniques (no direct local sources of Ozone).

Investigate the effect of idling vehicles at a designated school during student drop off and pickup times.

Investigate trackout/road dust issues

What We’d Expect to See

• Carbon Monoxide – 66% Transportation, 23% Industry

• Sulphur Dioxide – 92% Industry, 5% Transportation

• Nitrogen Oxides – 57% Transportation, 37% Industry

• PM10 – 73% Open Sources/Road Dust, 18% Industry

Note: MOE identified trackout/road dust resuspension as a major problem

Conclusions• These data are limited to Winter season and for

relatively short periods of time.• Point sources in the industrial area are sufficiently

close together that specific compounds needed to be used as tracers to separate impacts.

• Residential areas have relatively low levels of pollutants, however city impacts increase as distance downwind from the city edge increases.

• Concentrations increase sharply from residential areas to main roads, increasing again at intersections. Peak concentrations may increase by factors of 20-50.

• Time pattern of concentrations near intersections shows that idling vehicles at stop lights are a very significant source of pollutant exposure.

• Short survey near a school pickup and drop-off point showed that air pollution concentrations experienced by students can be significantly reduced by turning off engines in waiting cars.

Conclusions (contd)• Road dust includes elevated PM10, PM2.5 and PM1.• Trackout resuspension by large diesel trucks is a major problem. Some

levels doubled from same period in previous year.• 14 severe Trackout locations identified and monitored.• Peak ambient values of NO, SO2, PM10 and CO from 15 point sources were

quantified and ranked.• NPRI data rank industrial emissions in Hamilton in the order CO, SO2, NO

and PM10, and total emissions in the order CO, PM10 , NO, SO2. Mobile monitoring to date is showing an order of CO, PM10, NO, SO2, even in the industrial area.

• Large differences in distance from point source to fencelines heavily modify direct impacts compared to NPRI emissions data.

• Even allowing for distance variations there are significant differences between ambient and NPRI data for some sources. Other sources show good agreement.

• Mobile monitoring has different strengths than fixed network monitoring and both are necessary.

• Combination of simple GIS analysis and air pollutant monitoring proved very useful. A more sophisticated GIS analysis would be worthwhile.

• Data can be used to refine Regulation 419 models

Recommendations• Move cycle lanes off main roads, innovative signage.• Reduce idling emissions, including at school dropoff locations (enlist parent teacher

groups).• Monitor school bus idling.• Prioritize trackout reduction - paving, wheel washing, front gate dust monitoring.• Reinstate/enhance targeted road cleaning in industrial areas.• Reduce large diesel truck trips, it’s the combination of heavy trucks and dirty roads

that is a problem.• Gateway monitoring of diesel exhaust at city entry/exit points, industrial arterials.• Continue reducing point source remissions of SOx, NOx and PM10 (both ambient and

NPRI data) in order to improve/reduce health impacts.• Review existing fixed network stations and locations to refocus on adverse health

causing pollutants, e.g. NOx, monitoring gaps.• Compare mobile data to MOE STAC data, more detailed GIS analysis.• Review NPRI data variances with ambient.• Extend mobile monitoring to other seasons for more definitive source separation in

complex areas and documenting different met regime impacts, particularly inversions.• Extend mobile monitoring to other communities.• Use mobile data to refine local source inputs to Regulation 419 models.Disclaimer:- All recommendations and opinions are the sole responsibility of D.
